Ender 3D Printer Parts Silicone Socks/Aluminum Heater Block/Stainless Steel Throat for MK7 MK8 Extruder Kits Ender 3/Ender 3 Pro/Creality CR-10 /CR10S /S4 /S5 (3 Packs)

Becareful it doesnt come with the tension screw for heat element and lock screw for thermistor

Seems OK. Not sure why they anodized, would be cheaper and better if they included the set screw and thermo screw

These do fit correctly and function good but they do not give you the set screw for the heater cartridge or the screw for the thermosistor or even a new set to hold down the block. so if either of these screws are messed up on yours dont order these you will not recieve any screws at all.

Very happy with this vendor (on-time) and product. Copper heatsink and filament tubes machining is accurate . Have been purchasing complete heater assemblies. This replacement kit lets you trade out the hot parts of the head without having to re-snake and re-attach the leads. Smart up grade. Be sure to have a hand held Propane torch to loosen the screws from your existing assembly. Again a smart purchase if you have the tools!

So far only used one block after stripping out my original one on my Ender 3 Pro. There was absolutely no issue with alignment for me and everything has been working the months since with a lot of printing. However I am knocking off a star for not having any extra screws. I had almost lost my original screw twice during the swap and not having an extra wound of been very inconvenient and aggravating. If they start including the screws this would be a near perfect product in my opinion. Update: Even after about a hundred additional hours of printing and months later they are still holding up great. Not that its surprising as they are just chunks of aluminum after all. But there is no difference I can tell even with thousands of hours of printing between these and the ones I replaced. Flow is good, swapping nozzles is good, temps are good. It just works :)

For the price I paid (under $14.00) this is an excellent deal. Parts appear to be equal to the original Ender 3. Printing at 205C the silicone hood doesnt smoke or smell. I do wish the set included grub screws, but I still have to give it 5 stars for the value.

Fit my ender 5 pro with a gulfcoast robotic all metal hotend perfectly. The stock one would not stop leaking no matter what I tried and these new blocks finally fixed that. Quality and finish seem to be better than original so far. Would definitely recommend.

Im doing enough printing that Ive found its wise to have spares. Ive only ever had to replace one after a bit of a mess coated one with goo.

This product is not made correctly. They drilled the recesses for the mounting screws on the wrong side of the block so the thermistor hole is on the wrong side of the block.

Fits perfectly
